“gR”Indicates a fast fuse for full range protection.

4. Structural features

The melting tube of this product is made of special high temperature resistant materials, with high flame retardancy and strong hardness. The melt is made of 99.99% pure silver and is encapsulated in the melting tube. The molten tube is filled with chemically treated high Purity quartz sand and special chemical materials are used as the arc extinguishing medium. The contact surface is treated with silver plating to ensure reliable electrical performance and greatly reduce the temperature rise and power consumption. Both ends of the melt are firmly connected to the contacts by spot welding, which improves The safety and reliability of breaking short-circuit fault current is greatly enhanced
